I bought eggs from the BYC auctions (great sellers btw) and I had them shipped. When received a few had the air sacks moving in them. I put DOA on them and stuck them in the incubater (just in case). All but one didnt change. I removed them and examined the odd ball. To my surprise this little guy started growing but the air sack still floats around in the egg. We are on day 10. I have not turned this egg in hopes the air sack would set, but it hasn't. What are my odds of keeping this one alive and maybe a full hatching? Is there anything I can do to help it? Lock down is quickly approaching any advice would be great!
